- Better fit
Carry long Nordic skis
Published maximum ski length is at least 200 cm.
- Rhino-Rack MasterFit 530L

Fit bars set far apart

Pack for a family of four
For volume and gear length, Rhino-Rack MasterFit 530L records “18.7 cu ft. Gear up to 210.8 cm” and Thule Motion 3 XXL records “21 cu ft. Gear up to 215 cm”. Treat this as a hard limit on the size or amount that fits in one run. Shape can matter as much as the headline figure.
